A metaphor is a comparison between two things without using the words "like" or "as" (which would make it a simile). In this paragraph, the cyclops is compared to a large mountain. The effect of the metaphor is thus 1) to make a comparison and 2) to give the reader a visual image of the cyclops as a huge entity.
